Diodes - Zener - Single are special type of diodes with a specifically designed PN-junction and a specific reverse-bias voltage rating. RLZTE-115.1C is a single-zener diode designed for applications in circuits that require regulation and control by the use of a zener reference.

Application fields

RLZTE-115.1C is widely used for many applications including a voltage reference for comparators, an overvoltage protection or a current limiting device. It is also used as a voltage regulator in many DC to DC converters and battery-powered systems. Its low reverse leakage current and its low forward voltage drop as well as its low thermal resistance make it ideal for many high speed logic and driver applications.

Working principle

The RLZTE-115.1C relies on reverse-biasing to generate a voltage droop, controlled by the amount of current flowing through it. Because of the PN junction formed, when a certain voltage is applied to the diode, depending of the zener voltage rating, current begins to flow. This voltage, normally referred to as the zener voltage, is the reference voltage for the RLZTE-115.1C and is used to regulate a specific current for the application.

The voltage drop of the RLZTE-115.1C is directly proportional to the amount of current run through it. When a current is run through the diode, it works against the regulating voltage like a resistor, reducing the output voltage. The benefit of this type of regulation is that it allows the voltage drop to be modified simply by adjusting the current, which can be done with a set of resistors and capacitors.

Advantages

The main advantage of using RLZTE-115.1C as a voltage regulator is its low cost and high efficiency. The unique combination of PN junction and its low forward drop, make the diode suitable for many applications where a low voltage drop is needed. Also, by using the diode as a voltage regulator, the circuit is protected from overvoltages, since the RLZTE-115.1C will automatically limit the current running through it. This makes the diode not only a voltage regulator, but also an overvoltage protector.

Conclusion

The RLZTE-115.1C is an effective and low cost solution for applications that require voltage regulation and protection against overvoltages. Its unique characteristics make it ideal for many power supply and driver applications, where a low voltage droop is needed. Its low leakage current and low forward voltage drop also make it suitable for high-speed logic applications.
